System and method for automatically generating executable tests in Gherkin format

ABSTRACT

Various methods, apparatuses/systems, and media for automatically generating tests in Gherkin format are disclosed. A repository stores open application programming interface (API) specification definition file corresponding to an application. A processor accesses the repository to obtain the open API specification definition file as input data. A receiver receives the input data. The processor parses, in response to received input data, the specification to collect data from the open API specification definition file; structures the collected data into a data frame object; implements a processing logic to derive applicable tests using a predefined template; implements the tests by utilizing the predefined template; and automatically generates, based on the implemented tests, corresponding test cases in an executable Gherkin syntax. This process of automatically executing testing of the application based on the functional tests is performed, for example, on a Kubernetes platform.

TECHNICAL FIELD

This disclosure generally relates to software testing, and, more particularly, to methods and apparatuses for implementing an automatic test generating module for automatically generating executable automated application programming interface (API) integration tests in Gherkin format from an open API specification.

BACKGROUND

As software application becomes increasingly more complex, generating tests and testing such software application based on the tests also become more complex as a large number of unique combinations of paths and modules may be tested for each program. Conventional tools exist for generating tests for software application testing which generally require a significant amount of manual effort. For example, creating and maintaining application programming interface (API) functional integration tests manually is a time intensive process and requires specialist technical expertise, thereby significantly leading to a delay in generating the tests and testing and getting useful feedback for developers, and wasting computer resources on build servers.

Memories described herein are tangible storage mediums that can store data and executable instructions, and are non-transitory during the time instructions are stored therein. Again, as used herein, the term “non-transitory” is to be interpreted not as an eternal characteristic of a state, but as a characteristic of a state that will last for a period of time. The term “non-transitory” specifically disavows fleeting characteristics such as characteristics of a particular carrier wave or signal or other forms that exist only transitorily in any place at any time.

In accordance with various embodiments of the present disclosure, the methods described herein may be implemented using a hardware computer system that executes software programs. Further, in an exemplary, non-limited embodiment, implementations can include distributed processing, component/object distributed processing, and an operation mode having parallel processing capabilities. Virtual computer system processing can be constructed to implement one or more of the methods or functionality as described herein, and a processor described herein may be used to support a virtual processing environment.

As described herein, various embodiments provide optimized processes of implementing an auto-test generating module for automatically generating executable automated API integration tests in Gherkin format from an open API specification, thereby allowing both technical and non-technical users to generate and maintain these tests and save a significant amount of manual effort (approximately 60-70% of API regression test coverage), but the disclosure is not limited thereto.

Referring to FIG. 2 , a schematic of an exemplary network environment 200 for implementing an auto-test generating device (ATGD) of the instant disclosure is illustrated.

According to exemplary embodiments, the above-described problems associated with conventional test generating method and systems may be overcome by implementing an ATGD 202 as illustrated in FIG. 2 by implementing an auto-test generating module for automatically generating executable automated application programming interface (API) integration tests in Gherkin format from an open API specification, thereby allowing both technical and non-technical users to generate and maintain these tests and save a significant amount of manual effort (approximately 60-70% of API regression test coverage), but the disclosure is not limited thereto.

The ATGD 202 may be the same or similar to the computer system 102 as described with respect to FIG. 1 .

The ATGD 202 may store one or more applications that can include executable instructions that, when executed by the ATGD 202, cause the ATGD 202 to perform actions, such as to transmit, receive, or otherwise process network messages, for example, and to perform other actions described and illustrated below with reference to the figures. The application(s) may be implemented as modules or components of other applications. Further, the application(s) can be implemented as operating system extensions, modules, plugins, or the like.

Even further, the application(s) may be operative in a cloud-based computing environment. The application(s) may be executed within or as virtual machine(s) or virtual server(s) that may be managed in a cloud-based computing environment. Also, the application(s), and even the ATGD 202 itself, may be located in virtual server(s) running in a cloud-based computing environment rather than being tied to one or more specific physical network computing devices. Also, the application(s) may be running in one or more virtual machines (VMs) executing on the ATGD 202. Additionally, in one or more embodiments of this technology, virtual machine(s) running on the ATGD 202 may be managed or supervised by a hypervisor.

In the network environment 200 of FIG. 2 , the ATGD 202 is coupled to a plurality of server devices 204(1)-204(n) that hosts a plurality of databases 206(1)-206(n), and also to a plurality of client devices 208(1)-208(n) via communication network(s) 210. A communication interface of the ATGD 202, such as the network interface 114 of the computer system 102 of FIG. 1 , operatively couples and communicates between the ATGD 202, the server devices 204(1)-204(n), and/or the client devices 208(1)-208(n), which are all coupled together by the communication network(s) 210, although other types and/or numbers of communication networks or systems with other types and/or numbers of connections and/or configurations to other devices and/or elements may also be used.

The communication network(s) 210 may be the same or similar to the network 122 as described with respect to FIG. 1 , although the ATGD 202, the server devices 204(1)-204(n), and/or the client devices 208(1)-208(n) may be coupled together via other topologies. Additionally, the network environment 200 may include other network devices such as one or more routers and/or switches, for example, which are well known in the art and thus will not be described herein.

By way of example only, the communication network(s) 210 may include local area network(s) (LAN(s)) or wide area network(s) (WAN(s)), and can use TCP/IP over Ethernet and industry-standard protocols, although other types and/or numbers of protocols and/or communication networks may be used. The communication network(s) 202 in this example may employ any suitable interface mechanisms and network communication technologies including, for example, teletraffic in any suitable form (e.g., voice, modem, and the like), Public Switched Telephone Network (PSTNs), Ethernet-based Packet Data Networks (PDNs), combinations thereof, and the like.

The ATGD 202 may be a standalone device or integrated with one or more other devices or apparatuses, such as one or more of the server devices 204(1)-204(n), for example. In one particular example, the ATGD 202 may be hosted by one of the server devices 204(1)-204(n), and other arrangements are also possible. Moreover, one or more of the devices of the ATGD 202 may be in a same or a different communication network including one or more public, private, or cloud networks, for example.

The plurality of server devices 204(1)-204(n) may be the same or similar to the computer system 102 or the computer device 120 as described with respect to FIG. 1 , including any features or combination of features described with respect thereto. For example, any of the server devices 204(1)-204(n) may include, among other features, one or more processors, a memory, and a communication interface, which are coupled together by a bus or other communication link, although other numbers and/or types of network devices may be used. The server devices 204(1)-204(n) in this example may process requests received from the ATGD 202 via the communication network(s) 210 according to the HTTP-based and/or JavaScript Object Notation (JSON) protocol, for example, although other protocols may also be used.

The server devices 204(1)-204(n) may be hardware or software or may represent a system with multiple servers in a pool, which may include internal or external networks. The server devices 204(1)-204(n) hosts the databases 206(1)-206(n) that are configured to store metadata sets, data quality rules, and newly generated data.

Although the server devices 204(1)-204(n) are illustrated as single devices, one or more actions of each of the server devices 204(1)-204(n) may be distributed across one or more distinct network computing devices that together comprise one or more of the server devices 204(1)-204(n). Moreover, the server devices 204(1)-204(n) are not limited to a particular configuration. Thus, the server devices 204(1)-204(n) may contain a plurality of network computing devices that operate using a master/slave approach, whereby one of the network computing devices of the server devices 204(1)-204(n) operates to manage and/or otherwise coordinate operations of the other network computing devices.

The server devices 204(1)-204(n) may operate as a plurality of network computing devices within a cluster architecture, a peer-to peer architecture, virtual machines, or within a cloud architecture, for example. Thus, the technology disclosed herein is not to be construed as being limited to a single environment and other configurations and architectures are also envisaged.

The plurality of client devices 208(1)-208(n) may also be the same or similar to the computer system 102 or the computer device 120 as described with respect to FIG. 1 , including any features or combination of features described with respect thereto. Client device in this context refers to any computing device that interfaces to communications network(s) 210 to obtain resources from one or more server devices 204(1)-204(n) or other client devices 208(1)-208(n).

According to exemplary embodiments, the client devices 208(1)-208(n) in this example may include any type of computing device that can facilitate the implementation of the ATGD 202 that may be configured for implementing an auto-test generating module for automatically generating executable automated application programming interface (API) integration tests in Gherkin format from an open API specification, thereby allowing both technical and non-technical users to generate and maintain these tests and save a significant amount of manual effort (approximately 60-70% of API regression test coverage), but the disclosure is not limited thereto.

Accordingly, the client devices 208(1)-208(n) may be mobile computing devices, desktop computing devices, laptop computing devices, tablet computing devices, virtual machines (including cloud-based computers), or the like, that host chat, e-mail, or voice-to-text applications, of other document collaborative software for example.

The client devices 208(1)-208(n) may run interface applications, such as standard web browsers or standalone client applications, which may provide an interface to communicate with the ATGD 202 via the communication network(s) 210 in order to communicate user requests. The client devices 208(1)-208(n) may further include, among other features, a display device, such as a display screen or touchscreen, and/or an input device, such as a keyboard, for example.

Although the exemplary network environment 200 with the ATGD 202, the server devices 204(1)-204(n), the client devices 208(1)-208(n), and the communication network(s) 210 are described and illustrated herein, other types and/or numbers of systems, devices, components, and/or elements in other topologies may be used. It is to be understood that the systems of the examples described herein are for exemplary purposes, as many variations of the specific hardware and software used to implement the examples are possible, as will be appreciated by those skilled in the relevant art(s).

One or more of the devices depicted in the network environment 200, such as the ATGD 202, the server devices 204(1)-204(n), or the client devices 208(1)-208(n), for example, may be configured to operate as virtual instances on the same physical machine. For example, one or more of the ATGD 202, the server devices 204(1)-204(n), or the client devices 208(1)-208(n) may operate on the same physical device rather than as separate devices communicating through communication network(s) 210. Additionally, there may be more or fewer ATGDs 202, server devices 204(1)-204(n), or client devices 208(1)-208(n) than illustrated in FIG. 2 .

In addition, two or more computing systems or devices may be substituted for any one of the systems or devices in any example. Accordingly, principles and advantages of distributed processing, such as redundancy and replication also may be implemented, as desired, to increase the robustness and performance of the devices and systems of the examples. The examples may also be implemented on computer system(s) that extend across any suitable network using any suitable interface mechanisms and traffic technologies, including by way of example only teletraffic in any suitable form (e.g., voice and modem), wireless traffic networks, cellular traffic networks, Packet Data Networks (PDNs), the Internet, intranets, and combinations thereof.

Although only one repository 312 is illustrated in FIG. 3 , according to exemplary embodiments, a plurality of repositories 312 may be provided. The repository 312 may include one or more memories configured to store login information, data files, data content, API specification definition file (e.g., in JSON format) etc., but the disclosure is not limited thereto. For example, the repository 312 may include one or more memories configured to store information including: rules, programs, production requirements, configurable threshold values defined by a product team to validate against service level objective (SLO), machine learning models, log data, hash values, etc., but the disclosure is not limited thereto. According to exemplary embodiments, the ATGM 306 may be configured to be storage platform agnostic—configured to be deployed across multiple storage layers.

According to exemplary embodiments, the ATGM 306 may be configured to receive continuous feed of data from the repository 312 and the server 304 via the communication network 310.

As will be described below, the ATGM 306 may be configured to provide a repository that stores open API specification definition file corresponding to an application; access the repository to obtain the open API specification definition file as input data; receive the input data; parse, in response to received input data, the specification to collect data from the open API specification definition file; structure the collected data into a data frame object; implement a processing logic to derive applicable tests using a predefined template; implement the tests by utilizing the predefined template; and automatically generate, based on the implemented tests, corresponding test cases in an executable Gherkin syntax, but the disclosure is not limited thereto.

The plurality of client devices 308(1)-308(n) are illustrated as being in communication with the ATGD 302. In this regard, the plurality of client devices 308(1)-308(n) may be “clients” of the ATGD 302 and are described herein as such. Nevertheless, it is to be known and understood that the plurality of client devices 308(1)-308(n) need not necessarily be “clients” of the ATGD 302, or any entity described in association therewith herein.
